对于新墨西哥州法明顿周边疏散警报区内的人们来说,指令已经十分紧急。圣胡安县的一条紧急警报标注时间为2026年10月23日山区夏令时间上午9时刚过,称河水已漫过两岸,并要求受影响区域内的人们「立即撤离」。麦吉公园已开放,可接纳人员、宠物和休闲车辆。61
这条警报并未说明命令法明顿全市或圣胡安县全县撤离。警报描述的区域以法明顿为中心,但现有信息未明确具体街道边界。居民应听从应急官员针对具体地点发布的指示,而不是假定城市或县的名称就划定了疏散区。61
关键事实
情况恶化,超过了此前的预期。国家气象局阿尔伯克基办公室在上午9时57分发布的警报中称,上午9时河流水位为11.5英尺,并预测周五下午晚些时候将达到12.2英尺的洪峰。该办公室在上午10时42分发布的更新中称,上午10时河流水位已达到13.2英尺——比此前预报的洪峰高整整1英尺——并将下午洪峰预测上调至14.0英尺。1 2
这是一次大幅修正:两次警报之间,预报峰值上调了1.8英尺。但12.2英尺和14.0英尺都不是已经确认出现的洪峰。这两份警报中最新报告的观测值是上午10时的读数,并非报道发布时的实时测量。没有可用于核实这些报告读数的独立、带时间戳的水位站数据序列。1 2 3 5
高于洪水警戒水位,不代表水深
13.2英尺的读数意味着河水位比所述8.5英尺的洪水警戒水位高出4.7英尺。如果达到预报的14.0英尺洪峰,这一差值将变为5.5英尺。这些数字表示水位站记录的河流水位相对于固定基准的高度;并不意味着每条被淹的道路、每个院落或每栋建筑内的水深都是这个数值。实际情况取决于地点。2
这足以支持报道国家气象局关于水位超过历史纪录的评估,但不足以独立确认一项新的历史纪录。此前历史洪峰的原始记录,以及旧、新测量是否采用可比的水位站基准,均未得到确认。没有这种比较,简单地用一个水位减去另一个水位,无法定论这一历史纪录说法。3 5 15
另有一个需要分清的站点识别问题。法明顿的圣胡安河站点是USGS站点09365000,也标识为NWPS FRMN5。法明顿的阿尼马斯河站点是09364500;雪松山附近的阿尼马斯河站点是09363500。这些是不同的测量地点。名称中都带有「法明顿」,或影响到名为圣胡安的县,并不意味着它们的读数和预报可以互换。5 15 27 28
在查找缺失信息时,这一区别很重要。阿尼马斯河的读数无法证明圣胡安河是否已达到洪峰,雪松山的预报也无法补上法明顿洪峰的时间。圣胡安河的实际洪峰及其出现时间仍未得到确认。
避难所已开放,但没有逐条路线的解除警报通知
麦吉公园开放后,撤离人员有了一个明确目的地;那里可接纳人员、宠物以及休闲车辆。但这并不能证明每处受影响地点都有安全路线可达。现有报道未证实有任何道路、桥梁或公园因这次法明顿圣胡安河洪水而关闭。这一信息缺口并不意味着所有路线都可以通行。国家气象局警报要求驾车者不要绕过路障,也不要驶过被洪水淹没的区域。61 66 2
河水退去的预报时间也有所推迟。第一份警报预测,水位将在周六上午晚些时候(10月24日)降至洪水警戒水位以下。更新后的预报将这一时间调整为周六下午早些时候。两者都只是预报;即使观测到水位降至洪水警戒水位以下,也不能单凭这一点断定被淹路线可以安全重新开放。1 2
也不应把警报标注的到期时间误认为解除警报。较早发布的警报对结束时间提供了互相矛盾的信息:到期字段写的是周六下午4时(山区夏令时间),标题写的是周日中午,说明则延续到周日下午。这些时间不能被当作一个可靠的截止时间来呈现。1
较晚发布的警报列出的预定到期时间为10月25日星期日凌晨2时04分(山区夏令时间)。这是该警报注明的到期时间,并非经独立确认的实际行动结束时间,也不保证危险届时结束。消息的到期时间、警报所述事件结束时间,以及预报的水位降至洪水警戒水位以下时间,不一定一致。2
播出原貌 16 行
- The San Juan River has breached its banks.
- People in an alert area around Farmington have been told to evacuate. Major flooding is occurring, and McGee Park is open as a shelter. The actual crest and the timing of safe access are still unknown.
- The San Juan River at Farmington has its own measuring station. The Animas River at Farmington and the Animas near Cedar Hill have separate gauges. Their water levels and forecasts can't fill gaps in the San Juan's measurements.
- San Juan County's emergency alert told people in its affected area to “evacuate now.” Issued shortly after nine Friday morning, it said the river's banks had breached. The alert identified McGee Park as open for people, pets and RVs.
- The evacuation instruction covers an alert area centered around Farmington. Its exact street boundaries aren't clear, so residents need the location-specific instructions from emergency officials. The order can't be extended to everyone in the city or everyone across San Juan County.
- The river rose 1.7 feet in one hour. At nine a.m., it stood at 11.5 feet, with moderate flooding occurring. At ten a.m., it reached 13.2 feet, and the National Weather Service classified the flooding as major.
- Flood stage at this gauge is 8.5 feet. The earlier reading was three feet above that threshold. By ten a.m., the river was 4.7 feet above it. These are river-gauge heights, measured against a fixed reference. Water depth on a road or inside a property varies with the location.
- Weather officials raised the predicted peak by 1.8 feet. Their earlier forecast called for 12.2 feet late Friday afternoon. The update calls for 14.0 feet Friday afternoon. Both figures describe a forecast crest.
- A 14-foot crest would put the river 5.5 feet above flood stage. Officials haven't given a precise hour for that peak. The latest observation here is the ten a.m. reading of 13.2 feet. The river's final crest hasn't yet been confirmed.
- Weather officials say the river has exceeded the previous flood of record. They cite a crest of 12.3 feet on September sixth, 1909. Friday's 13.2-foot reading is numerically 0.9 foot higher than that historical figure.
- We don't yet know whether the old and new measurements use the same starting level. That leaves the historical comparison unsettled. If the river reaches the forecast 14 feet, it would stand 1.7 feet above the crest officials cite from 1909.
- McGee Park can accommodate people evacuating with pets and recreational vehicles. That gives residents in the affected alert area a named shelter destination. Emergency officials' instructions remain essential for choosing a safe route there.
- Weather officials now expect the river to fall below flood stage early Saturday afternoon, October twenty-fourth. Their earlier prediction was late Saturday morning. The revised timing is still a forecast, and falling water alone doesn't tell drivers whether a flooded route is safe.
- The earlier warning also gave conflicting end times. One field said four p.m. Saturday. Its headline said noon Sunday, while its description extended into Sunday afternoon. Those different times can't be treated as one reliable deadline for the danger.
- The later warning lists a scheduled expiration of two-oh-four Sunday morning, October twenty-fifth. An alert's expiration and the time the river drops below flood stage can differ. Residents still need emergency officials to confirm safe access.
- The immediate instruction for people inside the evacuation alert area is to leave, with McGee Park open for people, pets and RVs. Motorists must not drive around barricades or through flooded areas.
